Definition

1. Adjective:
   • Not harmonic; not related to or produced by musical harmony: Describes a musical note, tone, or element that is not part of the established harmonic structure or chord at a given moment. It is a note that creates dissonance or tension because it does not belong to the prevailing harmony.

Usage

• The term is used primarily in music theory and analysis to describe pitches that are foreign to the current chord or key. It is the opposite of "harmonic" or "chord tone."
• It functions as a descriptive adjective, typically placed before a noun (e.g., a nonharmonic tone) or used in a predicate (e.g., This note is nonharmonic).

Examples

• The composer used a nonharmonic passing tone to create a sense of movement between the chords.
• In this measure, the F-sharp is a nonharmonic note that resolves down to the E.
• Analyzing the piece involves identifying all nonharmonic tones, such as suspensions and appoggiaturas.

Advanced Usage

• Nonharmonic tones (NHTs): This is the most common advanced usage. It refers to specific categories of notes that are not part of the chord, including passing tones, neighbor tones, suspensions, appoggiaturas, escape tones, and anticipations. These tones are defined by how they are approached and how they resolve.
  • Example: "The student correctly labeled the suspension as a type of nonharmonic tone."

Variants and Related Words

• Dissonant (adj): Describes a combination of sounds that seems unstable and tense, often created by nonharmonic notes. While related, "dissonant" describes the sound quality, whereas "nonharmonic" describes the note's relationship to the chord.
• Chord tone / Harmonic tone (n): The direct antonym; a note that is a member of the sounding chord.
• Nonchord tone (n): A common synonym for "nonharmonic tone."

Synonyms

• Nonchordal
• Extraneous (to the harmony)
• Foreign (to the chord)

Antonyms

• Harmonic
• Chordal
• Consonant (in some contexts, though this refers more to sound stability than chord membership)
